Antoine Souma’s career has put him in front of enough families ahead of a wedding to recognize the exact moment when everyone at the table quietly avoids talking about the prenup. As founder of Galliott Capital Advisors, an independent boutique wealth advisory and extended family office serving entrepreneurs, global families, and multigenerational wealth holders, he has watched countless engagements move forward with toasts written and seating charts finalized while the big discussion remains unresolved and untouched, but still looming in the background.
Nobody wants to be the one who raises the question of a prenup first, and so the conversation gets delayed until it becomes someone else’s problem, sometimes a problem for the next generation to inherit at a far worse moment.

Why a Family Business Prenup Differs from an Ordinary One
A standard premarital agreement addresses two people and the assets they bring into a marriage. Souma sees a fundamentally different situation once a family business is part of the marital equation. Marrying into a family can mean bringing shares in an operating company, a governance seat that may eventually be available, and siblings whose ownership stakes are present on the same shareholder register.
Corporate structure has no awareness of romance. A cap table does not attend a wedding, and yet the family balance sheet remains quietly present behind every bride or groom at the altar, especially for high-net-worth families.
Souma sees it as the starting point for any conversation about premarital planning inside a family business, since the stakes surpass the couple exchanging vows. Advisors examining prenuptial agreements protecting family business shares consistently find that ownership complexity drives the need for these agreements.
The Real Issue Is Timing, Not Trust
Families typically mistake this conversation for a referendum on trust between two people in love. In his advisory work, Souma pushes back on that perspective. The actual variable determining if a family navigates this well has far less to do with trust and much more to do with when the conversation happens relative to the wedding itself.
“The mistake families make is thinking this conversation is about trust,” Souma says. “It was never about trust but timing, and the families who get the timing wrong pay for it in ways that have nothing to do with how much they loved each other.”
Souma walks clients through three contrasting scenarios drawn from his advisory practice. One family said nothing at all, judging the subject too heavy for a happy season, and years later a courtroom judge read their shareholder register aloud during a divorce proceeding that consumed two years of negotiation with someone who had never worked inside the company.
A second family raised the subject only weeks before the wedding, producing a signed document that technically held while leaving a lasting wound in the relationship it was meant to protect. A third family had resolved the matter decades earlier, embedding the structure into how ownership passed between generations long before any specific engagement existed, so that no one needed to spring anything on anyone once love entered the picture.
Structures With Duller Names Than Prenup
The distinguishing feature across those three outcomes, in Souma’s assessment, comes down to whether the arrangement gets attached to a specific person or built into the family’s standing architecture years in advance.
A restriction introduced immediately before a wedding inevitably reads as a judgment on the incoming spouse, regardless of how carefully worded the document is. The identical restriction, written into family governance long before any particular relationship exists, carries no such implication because it was never personal to begin with.
“None of this has to be labeled a prenup,” Souma explains. “Families that get this right didn’t find better words for the conversation. They found earlier ones, built into structures with duller names, signed during calm years instead of over an urgent dinner table.”
Souma works with families to build these protections into shareholder agreements, family constitutions, and trust structures well before children reach dating age, precisely so the eventual conversation never needs to happen in its rawest form.
Legal frameworks pairing a restrictive shareholder agreement with a premarital arrangement have become increasingly common among family enterprises seeking to keep ownership within the bloodline without singling out any particular in-law.
Families researching shareholder agreement and prenup structures for family wealth find that a standing family policy applied uniformly to every shareholder removes much of the sting that an individually negotiated agreement can carry.
What Silence Actually Teaches the Next Generation
Souma reminds clients that a decision to address or avoid the subject reaches past the couple standing at the altar. Siblings and cousins watch closely how a family handles its first engagement involving significant ownership, and that handling becomes a template every subsequent engagement inherits.
The next generation absorbs a lesson in real time regarding whether the family protects what it built through structure or through silence. Silence carries an obvious emotional appeal in the moment, sparing everyone an uncomfortable dinner-table exchange during a season meant for celebration.
Souma has seen that same silence produce far worse outcomes down the line, including the exact courtroom scenario where a shareholder register becomes public record during contested divorce proceedings. Families exploring protecting a family business from a divorce settlement find that courts routinely treat business appreciation during a marriage as a shared marital asset absent clear documentation establishing otherwise.
Building the Conversation Before It Attaches to a Person
Antoine Souma‘s perspective for family business clients is to separate the structural conversation from any single relationship. Governance around ownership, marriage, and divorce, settled before an engagement exists, strips the emotional charge from the discussion and turns a future spouse’s arrival into simple orientation.
“It was never about the paper but entirely about when you write it,” says Souma.
Families anticipating inheritance or business appreciation carry real risk, and research on prenuptial agreements and future inherited wealth shows assets not yet received remain exposed without early planning. Those who build the structure first spend less time before judges and more enjoying the wedding.
